Most people don’t think twice about doing laundry. Turns out, it’s one of the biggest sources of microplastic pollution on the planet.

In this episode, Steve Cross sits down with Max Pennington, co-founder and CEO of CLEANR, to break down how a random discovery turned into a real company solving a real problem. They get into what it actually looks like to build a physical product from scratch: prototypes, patents, manufacturing headaches, investor dynamics, and the kind of failures you don’t see on LinkedIn. This is a conversation about figuring it out as you go, and why “good enough” usually isn’t.

About Our Guest

Max Pennington is the co-founder and CEO of CLEANR, a company focused on removing microplastics from everyday water systems. With a background in chemical engineering from Case Western, he helped develop a patented vortex filtration system that captures over 90% of microplastics from laundry.

CLEANR has already launched its first product and is pushing toward a bigger goal: getting this tech built directly into washing machines and expanding into whole-home water filtration. Max is in the middle of building it, figuring out product, market, and scale in real time.
